Description

Technical Field

[0001] This utility model relates to the field of protective film technology, and in particular to a protective film tear-off structure. Background Technology

[0002] In the manufacturing process of electronic products, a large number of auxiliary materials are required. Among them, protective films are widely used. When peeling off protective films, an adhesive PET tear handle is typically used. This tear handle pulls the protective film to complete the peeling action. The tear handle has an adhesive area and a non-adhesive area. The adhesive area is used to bond or fix the protective film to the product. The non-adhesive area is for contact with the hand, preparing for the pulling and peeling action. Conventional tear handle designs are usually square. When encountering special assembly requirements, such as when the protective film is applied to both sides of the product, and the tear handle is positioned between the two sides, the pulling force on the tear handle increases when peeling off one side of the protective film first and then the other side, making the tear handle prone to breakage. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a protective film tear-off structure.

[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0022] A protective film tear-off structure, as shown in the reference. Figure 1 and Figure 2 The device includes a tear-off handle body 10, which comprises an adhesive area 11 and a tear-off area 12. The adhesive area 11 and the tear-off area 12 are integrally formed. The adhesive area 11 is adhesive-coated and is used to adhere the tear-off handle body 10 to the protective film. The tear-off area 12 is located outside the protective film and is used for tearing off the protective film. An arc-shaped portion 20 is provided at the connection between the adhesive area 11 and the tear-off area 12. The arc-shaped portion 20 is arc-shaped so that the connection position between the adhesive area 11 and the tear-off area 12 is arc-shaped. After the adhesive area 11 is fixed to the protective film, the tear-off area 12 tears off the protective film through the adhesive force of the adhesive area 11. The arc-shaped connection between the tear-off area 12 and the adhesive area 11 makes it less likely for the tear-off area 12 and the adhesive area 11 to break when the tear-off area 12 is to be torn by hand, ensuring that the force is evenly distributed and facilitating the tearing off of the protective film.

[0023] Furthermore, referring to Figure 1 and Figure 2 The adhesive area 11 is single-sided, with the adhesive side of the adhesive area 11 adhering to the protective film. It should be noted that the adhesive strength of the adhesive side of the adhesive area 11 is greater than that of the protective film, so that the protective film can be separated from the product under the peeling handle area 12.

[0024] Furthermore, referring to Figure 1 and Figure 2 The adhesive area 11 is made of PET material.

[0025] Furthermore, referring to Figure 1 A notch 111 is provided on the side of the adhesive area 11 away from the tear-off area 12. The notch 111 communicates with the outside. The notch 111 is rectangular and located in the middle of the side of the adhesive area 11 away from the tear-off area 12. It should be noted that the depth of the notch 111 is approximately 2mm. The notch 111 divides the adhesive area 11 into a first adhesive part 112 and a second adhesive part 113. The first adhesive part 112 and the second adhesive part 113 are sequentially adhered to the protective film. The notch 111 ensures precise alignment when applying the adhesive area 11. When a protective film is applied to both sides of a product, the adhesive area 11 needs to be applied to both sides of the product sequentially. The notch 111 is used to align the middle position of the front and back sides of the product, serving as a partition, so that the first adhesive part 112 is first applied to the protective film on one side of the product, and then the second adhesive part 113 is applied to the protective film on the other side of the product.

[0026] Furthermore, referring to Figure 1 The notch 111 is positioned directly opposite the arc-shaped portion 20, so that the connection between the notch 111 and the adhesive area 11 and the tearing area 12 is on the same horizontal line, thereby dividing the tearing area 12 into sections.

[0027] Furthermore, referring to Figure 1 The side of the tear-off area 12 away from the arc-shaped portion 20 is flush with the outer side of the second adhesive portion 113 away from the first adhesive portion 112. The arc-shaped portion 20 is located at the connection between the first adhesive portion 112 and the tear-off area 12. Therefore, the tear-off area 12 and the second adhesive portion 113 are located in the same area. When the tear-off body 10 is attached to the protective film, the first adhesive portion 112 is attached to the protective film on one side of the product, and the second adhesive portion 113 and the tear-off area 12 are located on the protective film on the other side of the product. When removing the protective film, the protective film attached to the second adhesive portion 113 is peeled off first by holding the tear-off area 12, and then the protective film attached to the first adhesive portion 112 is peeled off in transition to complete the removal of the protective film. The arc-shaped portion 20 between the first adhesive portion 112 and the tear-off area 12 can reduce the pulling force on the tear-off area 12 when removing the protective film attached to the first adhesive portion 112, so as to avoid the tear-off area 12 breaking.

[0028] Furthermore, referring to Figure 2 The tear-off area 12 includes a substrate layer 121, an adhesive layer 122, and a red Mylar layer 123. The substrate layer 121 is made of PET material, the adhesive layer 122 is double-sided adhesive, and the red Mylar layer 123 is bonded to the substrate layer 121 through the adhesive layer 122. The red Mylar layer 123 is red and is located on the same side as the adhesive side of the adhesive area 11. It should be noted that the red Mylar layer 123 serves as an identifier to help identify the tear-off area 12 and to allow for the removal of the protective film by holding the tear-off area 12.

[0029] Furthermore, referring to Figure 2 The thickness of the tearing area 12 is 0.1mm, and the length of the tearing area 12 is 5mm.

[0030] Furthermore, referring to Figure 1 The length of the tearing handle body 10 is 22mm, and the length of the tearing handle body 10 is the length of the second adhesive part 113 plus the length of the tearing handle area 12.

[0031] Furthermore, referring to Figure 2 The hardness of the tear-off area 12 is greater than that of the sticky area 11, so that the protective film can be more easily removed when holding the hand.

[0032] Furthermore, referring to Figure 2After the tear handle body 10 is attached to the protective film, the tear handle area 12 is raised relative to the adhesive area 11. The tear handle area 12 and the adhesive area 11 are not on the same plane, and the angle between the tear handle area 12 and the adhesive area 11 is greater than 30°. This makes it convenient to pull up the tear handle area 12 to tear off the protective film.

[0033] This invention divides the adhesive area 11 into a first adhesive portion 112 and a second adhesive portion 113 by providing a notch 111, allowing the first adhesive portion 112 and the second adhesive portion 113 to adhere to the protective film located on the front and back of the product, respectively. The adhesive area 11 and the tear-off area 12 are provided with arc-shaped portions 20. When removing the protective film, the protective film adhered to the second adhesive portion 113 is peeled off first by holding the tear-off area 12, and then the protective film adhered to the first adhesive portion 112 is peeled off in a transitional manner to complete the removal of the protective film. The arc-shaped portions 20 reduce the pulling force on the tear-off area 12 when removing the protective film adhered to the first adhesive portion 112, thus preventing the tear-off area 12 from breaking.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
